The 'Keeping Up With the Kardashians' star confirmed in December she's expecting her first child with boyfriend Tristan Thompson, and after keeping her pregnancy under wraps for months, she's now being more open with her fans and shared some new pictures of her growing bump.

She shared a photo of herself in a tight black dress and fur coat with her hand on her stomach and wrote on Instagram: ''Officially 6 months (sic)''

The 33-year-old star also shared a picture of herself and boyfriend sharing a kiss, and captioned it: ''Mom and Dad (sic)''

Khloe previously hailed her pregnancy as her ''greatest dream'' when she confirmed the happy news to her fans.

Alongside a photograph of her flaunting her burgeoning bump, with Tristan's hands wrapped around her stomach, which was shared on her Instagram account, she wrote: ''My greatest dream realized! We are having a baby! I had been waiting and wondering but God had a plan all along. He knew what He was doing. I simply had to trust in Him and be patient. I still at times can't believe that our love created life! Tristan, thank you for loving me the way that you do! Thank you for treating me like a Queen! Thank you for making me feel beautiful at all stages! (sic)''

The 'Revenge Body' star recently came under fire for working out while pregnant, but she has blasted her critics and vowed to continue sharing her fitness posts.

She hit back on Twitter: ''For the ones who think they are physicians all of a sudden. But MY doctor and I communicate and my workouts are cleared and highly recommended. Thanks kiddos! Don't make me stop sharing s**t (sic).''

Apart from dealing with criticism on social media, Khloe has had a ''pleasant pregnancy'' so far without any bouts of illness or morning sickness.

Speaking previously about how she is coping, a source said: ''Khloe has not had any morning sickness or had any less than pleasant pregnancy symptoms.''
